DETAILED DESCRIPTION

Example embodiments will now be described more fully with reference to the accompanying drawings. FIGS. 1 and 2 respectively show an aircraft 10 including a fuselage 100 with a window display 12 and an associated inner passenger compartment panel 11 according to the present teachings. The window display 12 is configured to be placed between an outer window member 14 of an aircraft passenger compartment 16 and an inner passenger compartment window 18. The window display 12 is configured to provide textual or graphical information to a passenger within the passenger compartment 16. As described below, the display 12 can be releasably fixed to the inner compartment window 18 for ease of repair or replacement. The inner passenger compartment panel 11 can include switches or capacitive sensors (not shown) which allow for the interface by the passenger with the contents of the display 12.

The display 12 includes a transparent (e.g. translucent) display member 20 (see FIG. 3) for transmitting information to the passenger. This transparent display member 20 can be an thin film transparent display member such as LCD display or a transparent thin film having associated OLEDs. Additionally, the display member 20 can be a projection display associated along the frame of the display member The thin film transparent display 20 has a controllable data transmission circuit 22 for varying the light transmission through or from the pixels 24 defined in the thin film transparent display member 20 (see FIG. 3 ).

As best seen in FIG. 3 , the controllable data transmission circuit 22 has a plurality of associated sensors (26, 28, 30) which can be used to vary the color or amount of light transmitted through each pixel associated with an image 32. Alternatively, changes the amount or color of or amount of light associated with the background 34 of the display member 20 can be automated to maximize visibility. Because of differences in altitude and positioning of the sun about the earth, there will be large variations in the amount of backlight passing through the outer window member 14 at any given time. Because of the changes in environmental conditions, the associated sensor 30 can be a temperature measuring sensor which will allow the circuit 22 to change currents to the display member as is needed to maintain visual quality or to protect the thin film display.

Additionally, as the internal cabin lighting may be changed during a flight, the visibility of information transmitted by the display member 20 for the passenger can be obscured. As such, the circuit 22 can include a pair of light receiving sensors 26, 28 which determine the amount of light passing through the window assembly and the inner passenger compartment. Both sensors 26, 28 provide a signal indicative of these light values. The controllable data transmission circuit 22 then will calculate a difference in the amount of light between the outside and inside of the cabin and adjust either the darkness or color of pixels sending transmitting information, or the amount of light transmitted through a background.

In the case of an OLED display, the amount of light transmitted by the OLEDS can be adjusted to adjust current or voltage to the OLED to change the visibility of pixels transmitting information or the temperature of the thin film display. Additionally, the display member 20 can incorporate capacitive touch sensors which will allow the passenger to interact with the window display 12 to change the image on the display 12. These touch sensors can use the electrodes of the OLEDS to convert the display member into a capacitive touch pad.

Optionally, the thin display member 20 can include a second layer of LCD or polarizable material (not shown) that can change the overall amount of light transmitted through the inner compartment window 18. It is envisioned that the display member 20 can be used to communicate safety information to the passengers such as a need to remain seated or fasten seat belts. Additional, as shown in FIG. 3 , information related to the location of the aircraft along a flight path, viewable items in the ground or sky of interest, or movies can be shown.

FIG. 4 represents an exploded view of the window according to the present teachings. Shown is the associated inner passenger compartment panel 11 which can be of the form of a wall panel or a window frame. As shown, the window display 12 is positioned between an outer window member 14 of an aircraft passenger compartment 16 and an inner passenger compartment window 18. To facilitate repair, the display 12 can be releasably fixed to the inner compartment window 18 for ease of access.

FIG. 5 shows a cross section through an aircraft window with the display member 20. The outer window member 14 and an inner passenger compartment window 18 can have a curved or flat configuration (i.e. planar or substantially planar cross-sectional shape). The outer surface 40 of the inner passenger compartment window 18 is spaced from or offset from the outer window member 14 and the defined fuselage contour. Disposed on the outer surface 40 is the display member 20 which is functionally positioned between the inner and outer window members (18, 16). By coupling the display member 20 to the outer surface 40 of the inner passenger compartment window 18, the display member 20 can be protected from passenger contact. This additionally allows for a frame 42 to be used as a support for the display member 20 and an electrical connector (not shown) for data and power transmission.

Examples of suitable materials for the outer 14 and inner window panels 18 can include, but are not limited to, plastic materials (such as acrylic polymers). Such as polyacrylates; polyalkylmethacrylates, such as polymethylmethacrylates, polyethylmethacrylates, polypropylmethacrylates, stretched acrylic, and the like; polyurethanes; polycarbonates; polyalkylterephthalates, such as polyethyleneterephthalate (PET), polypropyleneterephthalates, polybutylene terephthalates, and the like; polysiloxane-containing polymers; or copolymers of any monomers for preparing these, or any mixtures thereof); glass, such as conventional soda-lime-silicate glass (the glass can be annealed, heat treated, or chemically tempered glass); or combinations of any of the above.

The inner window 18 and outer window 14 are preferably transparent to visible light. By “transparent” is meant having visible light transmission of greater than 0% up to 100%. Alternatively, one or both of the panels 12, 18 can be translucent. The display member or inner or outer window members (14, 18) can include for instance a film which acts a polarizer or light filter which filters out certain incident light frequencies.

FIGS. 6-14 illustrate another embodiment for providing a display for the aircraft 10. Referring to FIGS. 1, 6-9, and 14 , as discussed above, the aircraft 10 includes a fuselage 100 that surrounds an aircraft interior 102. Incorporated into the fuselage 100 is a sidewall assembly 104. The sidewall assembly 104 includes a sidewall portion 106 of the fuselage 100 that includes an inner-facing side 108 disposed adjacent to the aircraft interior 102 and an outer-facing side 110 disposed opposite the inner-facing side 108 adjacent to the outside of the aircraft 10.

Referring to FIGS. 6-9 and 14 , in an exemplary embodiment, the sidewall assembly 104 includes a plurality of windows 112 and 114 that are spaced apart and that are partially or fully surrounded by the sidewall portion 106. As illustrated, a transparent display panel 116 is coupled to the sidewall portion 106 covering the inner-facing side 108 of the sidewall portion 106 including the windows 112 and 114. In an exemplary embodiment, the transparent display panel 116 includes one or more display screens 118 a-b that independently display information (e.g., different information) to a passenger(s) 120 in the aircraft interior 102. In an exemplary embodiment, the transparent display panel 116 is a transparent OLED panel and the display screens 118 a-b are OLED display screens. In an exemplary embodiment, the transparent display panel 116 has a relatively large screen size of about 55 to about 90 inches for advantageous viewing.

Referring also to FIG. 14 , in an exemplary embodiment, a display controller 122 is in communication with the transparent display panel 116 to communicate video/audio signals 124 and 126 providing corresponding information to the display screens 118 a and 118 b. As illustrated, the display controller 122 may be controlled by the passenger 120 or other occupant of the aircraft 10 via a user input device 121 (e.g., hand-held controller, personal computing device or the like) to direct the display controller 122 to communicate the video/audio signals 124 and 126 to the various display screens 118 a and 118 b.

In an exemplary embodiment, the display controller 122 is in communication with a cabin management system (CMS) 128. Among various functions, the CMS 128 is configured to control various cabin environmental functions such as temperature, lighting, galley services, and in-flight entertainment which includes audio, video, interfaces to personal electronic devices, access to media content storage (audio & video files), satellite TV, and moving map equipment as well as access to long-range satellite communications and internet connectivity. As illustrated, the CMS 128 is in communication with an avionics system 130, an internet gateway 132, and an audio-video database 134, which contains a plurality of audio-video information and/or a plurality of movies, and provides information to the display controller 122 corresponding to temperature information, safety information, audio/video information, movies, financial market information, internet accessed information, flight information, and/or viewable items outside the aircraft. Independently, the display controller 122 may be in direct communication with the audio-video database 134 to access the audio-video information and/or movies for communication to one or more of the display screens 118 a and/or 118 b. In one example, the display controller 122 accesses the audio/video database 134 (e.g. directly or through the CMS 128) to communicate video/audio signals 124 to the transparent display panel 116 for display of a movie (e.g., audio/video information) on the display screen 118 a, and independently accesses the avionics system 130 (e.g., through the CMS 128) to communicate video/audio signals 126 for display of flight information on the display screen 118 b.

In an exemplary embodiment, the user input device 121 is used to switch the transparent display panel 116 on and/or off. In one example and as illustrated FIGS. 6 and 14 , the transparent display panel 116 is turned to an “on condition” that enables or otherwise powers the display screens 118 a and/or 118 b to display corresponding information as discussed above. In another example and as illustrated in FIGS. 7-8 , the transparent display panel 116 is turned to an “off condition” where the transparent display panel 116 is transparent to allow the inner-facing side 108 of the sidewall portion 106 including the windows 112 and 114 to be visible through the transparent display panel 116 to the passenger 120. As such, the passenger 120 can view clearly through the transparent display panel 116 and the windows 112 and 114 to outside the aircraft 10 when the transparent display panel 116 is in the “off condition.”

Referring to FIGS. 7-14 , in an exemplary embodiment, the sidewall assembly 104 includes a window shade 136 for each of the windows 112 and 114. The window shade 136 is disposed between the window 112 or 114 and the transparent display panel 116. Each of the window shades 136 are movable between an open position (as illustrated on FIGS. 7-9 ) to allow light to pass between the windows 112 and 114 and the transparent display panel 116 when the transparent display panel 116 is in the “off condition” and a closed position (as illustrated in FIGS. 10 and 12 ) to obstruct light from passing between the windows 112 and 114 and the transparent display panel 116 when the transparent display panel 116 is in the “on condition,” for example to enhance viewing of the display screens 118 a-b.

To further enhance viewing of the display screens 118 a-b, in an exemplary embodiment, the sidewall assembly 104 includes a movable blackout panel 138 (e.g. black opaque panel) for each of the windows 112 and 114. The movable blackout panel 138 is disposed between the corresponding window shade 136 and the transparent display panel 116. In an exemplary embodiment, the display controller 122 is in communication with a blackout control device 140 that is operable coupled to the movable blackout panels 138 to move the panels 138 between a retracted position (as illustrated on FIGS. 7-9 ) that allows light to pass between the windows 112 and 114 and the transparent display panel 116 when the transparent display panel 116 is in the “off condition” and an extended position (as illustrated in FIGS. 10 and 12 ) that obstructs light from passing between the windows 112 and 114 and the transparent display panel 116 when the transparent display panel 116 is in the “on condition.” As such, with the movable blackout panels 138 and the window shades 136 in the retracted/open positions, the passenger 120 can see clearly through the transparent display panel 116 and the windows 112 and 114 to outside of the aircraft 10. Likewise, with the movable blackout panels 138 and the window shades 136 in the extended/closed positions, enhance viewing of the display screens 118 a-b to the passenger 120 is provided because the area behind the transparent display panel 116 is blacked out by obstructing outside light from passing through the windows 112 and 114 into the area behind the display screens 118 a-b.

In an exemplary embodiment, the blackout control device 140 is further configured to move the window shades 136 between the open position and the closed position. In one example, the display controller 122 communicates command signals to the blackout control device 142 move the window shades 136 independently or together with movable blackout panels 138 between the open/retracted positions and the closed/extended positions.

Referring to FIGS. 7-8 and 10-13 , in an exemplary embodiment, the sidewall assembly 104 includes a transparent covering 142 that is disposed adjacent to and covers the transparent display panel 116. For example, the transparent covering 142 is a plastic sheet formed of a transparent or amorphous polymeric material, such as, for example polymethylmethacrylate (PMMA), polycarbonate (e.g., Lexan), or the like.

As illustrated, a ledge 144 is disposed adjacent to the inner-facing side 108 of the sidewall portion 106 extending under the transparent display panel 116 and the transparent covering 142 towards the aircraft interior 102. In an exemplary embodiment, the ledge 144 is both a functional and aesthetical trim piece that provides an understructure for supporting the transparent display panel 116. Additionally, the transparent display panel 116 is secured to the sidewall portion 106 via fasteners 146.
